Four gases A, B, C and D have critical temperatures 5.3, 33.2, 126.0 and 154.3K respectively. For their adsorption on a fixed amount of charcoal, the correct order is: (A) CDBA (B) CBDA (C) DC

Question

Four gases A, B, C and D have critical temperatures 5.3, 33.2, 126.0 and 154.3K respectively. For their adsorption on a fixed amount of charcoal, the correct order is:

(A) C>D>B>A
(B) C>B>D>A
(C) D>C>B>A
(D) D>C>A> B

Prashant Kotian · Accepted Answer

Correct answer: C. Gas which has higher value of critical temperature shows more adsorption or get easily liquefied.
